Another object is to provide a device of the character and for thepurpose above set forth which is readily portable, has a minimum numberof parts, which may be quickly and easily assembled or disassembled,when desired, is inexpensive to manufacture and obviates bolting ornailing to the cross arm to which it is attached.

To the accomplishment of the above, and the subordinate objectspresently appearing, a preferred embodiment of my invention has beenillustrated in the accompanying drawings, set forth in detail in thesucceeding description, and deflned in the claim appended hereto.

In said drawings:

Figure 1 is a view in side elevation, partly in section, illustratingthe preferred embodiment of my invention applied,

Figure 2 is a View in front elevation,

Figure 3 is a View in rear elevation,

Figure 4 is a view in top plan,

Figure 5 is a view in vertical transverse section taken on the line 5-5of Figure 2, and

Figure 6 is a view in bottom plan of the clamp.

Reference being had to the drawings by numerals, I have shown myimproved support therein as attached to one of the usual, transverselyrectangular, cross arms I of a telegraph pole, represented at 2, thesupport being designated as a unit by the numeral 3.

The basic element of my improved support is a rectangular clamp designedto fit entirely around the cross arm I and comprising a pair of opposed,sheet metal, angle plates 4, 5, having top flanges 8 and I, laterallyspaced side flanges 8, the top flange 6 of plate t overlapping thecorresponding flange 1 of the other plate 5, said top flanges 6, I,being detachably connected together and for relative adjustment of theplates i, 5, toward and from each other respectively, to increaseordiminish the width of the clamp. The connection between said flanges6, 1, takes the form of a central slot 9 in one flange, for instance 6,extending lengthwise transversely of the clamp, the bolt l0 extendedupwardly through the other top flange I through said slot and wing nut Hon the outer end of said bolt.

Detachably secured, by means presently described, to the side flange 8of the plate 4 is a pulley supporting arm l2 extending upwardly abovethe clamp for a suitable distance and then laterally so as to offset apulley l3 suspended from its upper end laterally of the cross arm iclear thereof. The pulley supporting arm I2 is formed of flat, bar-likemetal and is secured at its lower end flat against the flange 3 of platedby a pair of bolts l4 extending outwardly of the clamp and equippedwith wing nuts IE on the outer ends thereof. Above the plate 4, or saidclamp, said arm 12 is twisted to dispose the remainder of the arm withits edges in a vertical plane and thereby prevent said arm from flexingunder the weight of the load thereon. The pulley I3 is connected to theupper end of said arm l2 by a link it extended through an aperture H inthe arm. A hoisting cable, shown at E23, by dotted lines, is providedfor said pulley.

Opposed to the outer face of the side flange 8 of the plate 5 is a hingeplate 8 of substantially the same size as flange 8. A bolt I9 extendedoutwardly through the center of the flange 8 through a vertical slot 20in said plate 3' and equipped with a wing nut 2| detachably secures thehinge plate 8 to the flange 8 and for vertical adjustment thereon.Hinged to the bottomedge ofthe hinge plate 8, as at 22, is a bottomplate 23 for the clamp adapted to be swung upwardlyinto clampingposition and to extend in such position well beyond the side flange 8 ofthe plate 5, Opposed to the outer face of the lower end of the pulleysupporting arm i2 is the flattened end 24 of a vertically disposed bolt25 secured, to said end of said arm I? by the bolts'ltl and wingi nuts[5 and having a threaded lower end depending through a suitably arrangedslot 26 in the bottom plate 23 and equipped below said plate 23 with asuitable nut .27 whereby said bottom may be locked in clamping position.I

As will be readily understood, by removing the" nut 21 from the bolt 25,the bottom plate 23' the clamp may be swung downwardly from clampingposition to open the bottom of the clamp so that the plates 4, 5, may beplaced over the cross arm I in straddling relation thereto after whichthe bottom plate 23 may be swung upwardly against the bottom of the armI and secured in clamped position relative thereto by nut 21 and bolt24. By means of the wing nuts ll, 2|, bolts l0, l9 and slots 9 and 20,the plates 4, 5, may be adjusted into different set positions toincrease or plate diminish the width of the clamp in accordance withdifferent sizes of cross arms I, and by means of the wing nut 2|, boltl9 and slot 20, together with the nut 21 and bolt 25, the bottom plate23 may be vertically adjusted to increase or diminish the height of theclamp for the same purpose.

As will be manifest, by virtue of the rectangular shape of the describedclamp and the described adjustments of its parts, it may be so fitted todifferent sizes of cross arms i that tight clamping of the parts of theclamp against said arm need not be resorted to, unless desired, suchtight clamping not being essential to prevent the clamp and the arm I2from twisting around the cross arm I when the clamp is properly fittedto said cross arm.

The foregoing will, it is believed, suffice to impart a clearunderstanding of my invention without further explanation.

Manifestly the invention, as described, is susceptible of modificationwithout departing from the inventive concept, and right is hereinreserved to such modifications as fall within the scope of the subjoinedclaim.

What I claim is:

A device for attaching a hoist standard to a cross bar of a telephonepole comprising a clamp of rectangular form including a pair of opposedangle plates forming the top and sides of the clamp and connectedtogether for relative sliding adjustment laterally to vary the width ofthe clamp, a bottom forming plate for said clamp mounted on one of saidpair of plates for swinging movement into and from clamping relation,said bottom plate extending in clamping position beyond the outer sideof one of said pair of plates and having a slot therein, a bolt attachedto said outer side of said one plate and depending through said slot,and a nut on said bolt for turning against the bottom forming plate tohold the latter in clamping position, said bolt being adapted forcoaction with said outer side of said one plate to clamp a hoiststandard therebetween.
